Factoring

What is the GCF?
 $28p^3+16p^2+16p$  

•  $2p$  

•  $4p$  

•  $4p^2$  

•  $8p^{2\ }$  

Factor out the GCF:
 $56x^2-40x+80$  

•  $8\left(7x^2-5x+10\right)$  

•  $4\left(14x^2-10x+20\right)$  

•  $8\left(7x^2-40x+80\right)$  

•  $8\left(7x^2+x-10\right)$  

Factor out the GCF:
 $18x^6+16x^3+14x$  

•  $2x\left(16x^5+14x^2+12\right)$  

•  $2x\left(18x^5+16x^2+14\right)$  

•  $2x^2\left(9x^4+8x^2+7x\right)$  

•  $2x\left(9x^5+8x^2+7\right)$

20x³-25x²+4x-5

• (5x²-5)(4x+1)
• 5(x²-1)(4x+5)
• (5x²+1)(4x-5)
• (5x²+1)(4x-1)
